SIPHON-PUMP.

SPECIFICATION-formng part of Letters Patent No. 232,525, dated September 21, 1880,

Application filed January 7, 1880.

To all whom it may concern:

Be it known that I, VOLGOTT B. MAN- WARING, of New London, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Siphon-Pumps, and I do hereby declare that the followingl is a full, clear, and exact description of the same.

My invention rela-tes to siphon-pumps of` that class in which a collapsible bulb or similar exhausting device is used to give the first impulse to the liquid to be moved, the liquid continuing afterward to follow by the action of the Siphon, and said air-exhausting device being separated from the flow of the liquid.

The object of the invention is to simplify the details and to render the parts more efficient in operation.

The apparatus is more especially designed for use in connection with kerosene-oils or corrosive liquids, which would injure the air exhausting or pumping device.

The details of construction I have fully set forth hereinafter, and specically pointed out in the claims. s

In the drawings hereunto attached, and forming part of this specification, Figure 1 is a perspective of my improved pump, showing the mode of use. Fig. 2 is a section taken across the valves. Figs. 3 and 4' represent modifications, and Fig. 5 shows a modified form of valve-stop.

In these drawings, A represents a rectangular chamber, in which are located the clackvalves a b. Of these two valves, b is located at the mouth of the pipe B, through which the liquid enters into the liquid-chamber A, and C represents the exit-pipe opposite the valve a, from which the liquid is discharged. The valve b opens inwardly toward the chamber, and the valve a outwardly from the chamber.

On the top of the box or chamber Ais placed a. conical tube or aircl1amber, D, having at its upper and smaller end a hollow lug, d. The

conical tube or chamber opens into the chamber A, and upon the lug d is placed a hollow collapsible bulb, E, of ordinary construction, and adapted to expand forcibly after collapse.

The valves c b are located on proper seats, preferably at an inclination to the opening through which the liquid is drawn. Instead of lbeing hinged the valves may be held in place by straps h h or by the partition K.

These straps are of a shape as shownparticu- [arly in Fig. v2. They are inclined at an angle to the valve-seat at a distance sufficient to allow the-valve to open, in order to admit free tlow of the liquid. These guards or straps h may be made so as not to approach the valveseat in a direct line, but may be provided with an offset, t'. The object of this is to allow the valve, when lifted by the liquid, to rise clear from the seat, whereby its action is more free and there is less liability to clog. It will also be observed that the valves are simply plain plates made long and narrow, in order to be acted upon more readily, and that they are located on continuous sides of the chamber. Instead of the gua-rd or strap 71, the upper valve, a, is covered by a close hood, 7c, having the shape in cross-section similar to that of the strap h, heretofore described.

The modification of the pump shown in Fig. 3 contains also a modied form of the valve. In this modification, instead of the strap by which the valve is permitted to rise bodily from its seat, and at the same time is restrained within certain limits of motion, I have shown a valve pivoted or having bearings placed at a little distance from the rear of the valve, and held in position within certain limits of movement by loops and loose bearings x These permit the valve to drop freely upon its seat, but also allow the rear to rise bodily from the seat. That part of the valve which extends backward from the pivots bears against a iange, which, together with the loops, regulates the angle of elevation of the valve. In the figure referred to the partition between the two valves forms the iiange for the upper valve.

There is, therefore, no egress for the liquidV out of the chamber A into the pipe C, except through the `valve a. As the valves are located the fio w of the liquid from B through the valves b is direct to the valve a, and the liquid, under the impulse of the suction created by the expansion of the rubber bulb, will not rise into the upper part of the air-chamber D, so as to enter the bulb, which is located at the top of the conical or wedge shaped air chamber. The rubber bulb therefore is not liable to suffer IOC from the corrosive effects of the hydrocarbon oil or other liquid which may be pumped.

The modiication of my invention shown in Figs. 3 and 4 does not differ essentially from the form heretofore described. The chamber A in Fig. 4 is elongated, and the valves m n are placed on seats in inclined partitions on the same level.

The pipe Mis the exhaust, and Nis the discharge-pipe; and instead of the conical pipe D a Wedge-shaped chamber, O,is placed on the upper side of the box between two valves, and is provided with a collapsible bulb, the same as that heretofore described.

The action of the apparatus may be easily understood from the description of its construction. When the bulb is collapsed by force applied outside, the air is expelled through the upper valve, a, or the outer, m, and through the pipe C or N. When the bulb is permitted -to expand, tending to create a vacuum, pressure from the outside closes the valves a or m, and opens the valves b or n, forcing through the latter the iiuid into which the lower end of the pipe B or M is immersed. The second collapse of the bulb closes the valve b or n, and opens the valve a or m, through which latter the liquid finds egress, as the pipe C or N is made longer than pipe B or M. The flow once established becomes continuous until checked, orvuntil it ceases by reason of the exhaustion of the liquid.

I am aware that siphonpumps adapted to be set in motion by a collapsible bulb acting between two valves are not new.

I do not claim in this application an elongated horizontal chamber provided with suction and discharge pipes and inclined valves for facilitating the ilow of liquid, for this construction is shown and claimed in another application filed by lne for'Letters Patent and now pending.

What I claim, therefore, as my invention l. In a Siphon-pump, the combination, with the chamber A, of the clack-valves a and b, the pipes B and C, the pipe D, andthe collapsible bulb E, the parts being combined and operating as set forth. y

2. The combination, with the long loose valve adapted to rest upon itsseat, of the inclined guard or strap, as set forth.

8. The combination, in a siphon-pump, of a conical or pyramidal air-chamber and a collapsible bulb with the pipes and valves, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
